To all-whom itmag concern:

Be it known that I, JOSEPH M. BARTON, a citizen of the United States, residingat Danvers, in. the county of Essex and Commonwealth of Massachusetts, have inventeo certain Improvements in HeelAttaching Machines, of which the following-' description, in connection with the accompanying drawings, is a specification, like reference char" ctefs' on" the '-'drawings indicating }like parts in the several'figures.

This invention relates to heel attaching machines.

Where theheels of boots or shoes-are surface-nailed, they are attachedby nails driven" through both the toplift and the'heel into the heel 'seat, the ends of the nails' b'eing-ero posed to view in-the outer surface-of the top. lift. Heretofo're in this work it'hasbeen" custoniaryto secure top lifts to heels-before the heel attaching operation, this being com monly done in the operation of building-the e s-.-I

The primary object of the presentinvention is to makeprovision for attaching toa shoetwo separate superposed sections of a heels To this end an important feature of the invent-ion consists in a holder adapted to retainf in position to be attached a pluralityof superposed separate sections'to form a heel,- said helder beingso constructed and "a'r-. ranged that it may accommodate sections of, different sizes so that shoes of different sizes may be conveniently provided with, heels. In order that the sections to form the heel may be securely held in position to be at tached, the holder is preferably constructed to exert gripping pressure upon the individual sections, in the plane of 'each section;

Sincethe top lift serves as a age in the 1- heeltrimming operation, the position of its rounded end upon, the shoe should be determined independently of variations in size of the top lift The holder herein shown is accordingly so constructed that variations in size of the top lift, such, for example, as may be due to irregular shrinkage, are taken care ofatthebreast'ofthe top lift, the curvedend of the lift being maintained in a predetermined position. The holder-herein shown is. also so constructed thatirreg'ularities in' size-of the heel are taken care of at the rear'of the heel; To this end the holder is so formed that the breast edges of the heel and "the-top lift are maintained in approximately the same vertical plane.-

In the particular embodiment of the-im or outer section ofthe heel, a movable rear.

gagearranged for engagement-with an inner' section of the heel and constructed for rearward yielding ;;movement, and a breast gage arranged 'for engagement with the breastedges ofeachof said'sections and held yieldingly toward the rear gage. The relati-ve position of the two sections at the breast is determined by the contour of'the face of the breast gage, and the position of the curved end of 'the top lift or outer secti'on withreferenceto the driver passages of the machine may be variedby'adjus'tment of thestationary rear gage. The movable rear gage, by its yielding'movement, compensates for any irregularity in the size of the inner section of the heel.

It will be understood that while the present invention is herein described with reference to attaching heels and top lifts, itmay be employed to advantage in other cases where it maybe desired to attach to ashoeitlwo1 separate sections which are to form'a In the drawings, Figure 1 is a view in pers ective of a portion of a heel attachingm a c ine equipped witha nolder constituting one embodiment of the invention; Fig. 2'is'a" plan view of the holder and its supporting," plate; Fig. 3 is a fragmentary view in ver'-' tical; section, takenon the line 3-3 of 'FigJQJ Re'ferring'to the drawings, the reference numeral -1 indicates the nail "block head'of a heel attaching machine. The machine to which the invention is shoW'n'n-pplied-is illustrated and described morefully in IJet ters Patent of B. F. Mayo No. 884,513, granted April 14, 1908. Upon the head l is"-pivotallymounted=at i a plate 6. The plate 6 is arranged forswinging movement across the upper surface of'th'e headand carries a holder constructed to grip'individually two superposed sections adapted"toform a heel. The holder comprises two rean gages and a breast gage between which the sectionsof-the heel are gripped The-rear gages are arranged in a superposed relation shank 8 which'is received in a suitable guidethe shoe.

forward end with a fork 12 formed and arway upon the plate 6 formed between said plate 6 and a superposed plate 7 secured thereto. The shank 8 of the lower gage is provided at its rear end with a lug 9 entered by an adjusting screw 10 by which this gage may be adjusted longitudinally of The shank 8 is provided at its ranged to haveengagement with therounded end of the lower section of the heel. The upper rear gage, which rests upon the lower gage, has .at its forward end a fork 14 formed for engagement with the upper section of the heel, and its shank is provided with an upwardly extending projection 15.

' A rod 16 extends rearwardly from the projection 15 and enters an orifice in the lug 9 formed upon the end of the shank 8. A coiled spring 18 is arranged about the rod 16 between the projection 15 and the lug 9, and. presses the fork 14 forwardly, its for- Ward movement being limited by the contact of the projection 15 with the end of a 22. As will appear from Fig. 3 the inner.

surface of the gage, which has contact with the breast edges of the sections of the heel, is vertical and is of sufiicient height to have contact with both' sections of the heel. The lowerfork 12 is preferably of a height less than the thickness of the thinnest toplift which may be desired to be attached, so that when the sections of the heel are pressed against the heel seat said fork will be free from engagement with the upper section of the heel.

Prior to use of the mechanism shown and described, the lower fork 12 is adjusted longitudinally of the heel to insure that the rounded end of the top lift will be in correct position longitudinally of the shoe. The position of this fork is varied where change is made in the size of the top lifts.

being attached. The normal position of the breast gage 20 may also be adjusted in the manner indicated in the patent above referred to.

In the use of the holder shown, a heel blank and a top lift may be placed together in position therein, the breast gage being retracted to permit the insertion of the two superposed sections of a heel. As will appear from Fig. 3, the top lift rests directly upon the upper surface of the nail block, the plate 6 prior to the. attaching operation being in the position shown in Fig. 1. The breast gage being released, the sections of the heel are pressed rearwardly into engagement with the rear gages. The pressure exerted by the breast gage upon the two sections of the heel imparts to them a slight rotatorymovement in case their longitudinal axes are out of parallelism withthe longitudinal axis of the holder, and thus straightens their breast edges. The lower fork 12 limits rearward movement ofthe top lift while the upper fork 14 yields to the pressure exerted upon it by the upper section of the heel. To permit this operation,

the tension of the spring 22 is suflicient to overcome the resistance of the spring 18. Variations in length of the upper section'of the heel are thus taken care of by the yielding movement of the fork 14. It will be understood that the forks 12 and 14 center the rounded ends of the two sections of the heel. The position of each section of the heel in the holder is'thus accurately controlled and the two sections are gripped individually and securely held from displacement.

In the attaching operation the attaching nails are driven through 'the two sections of the heel into the heel seat. As the nail block head 1 descends after the nails are driven, the plate 6 is automatically swung laterally in the mannerindicated in the patent above referred to. This brings beneath the heel a spanking portion of the plate6 which is pressed against the heel in the second upward movement of the head 1 and evens up the surface of the heel, insuring that the ends of the nails will be flush with the surface of the top lift.

While in the holder shown the breast edges of the heel sections are maintained flush with each other, it will be understood that it would be within the present invention to so construct the holder that said edges would not lie in the same vertical plane. The arrangement shown, however, may be advantageous if'it is desired that the excess of stock in theupper section of the heel shall lie at the rear of the heel.

As will be obvious, changes may be made in the general arrangement of parts without departing from the present invention. I believe that I am the first to provide a heel attaching machine with a holder for gripping a plurality of superposed sections of a heel adapted to accommodate differing lengths of one or more of the sections and hold them in position to be attached, and I desire to claim the same broadlyin whati ever specific form it be embodied,
